Patent JP-2002360975-A (JP)
Title: Washing machine and washing and drying machine
Inventor: HIYAMA ISAO
IPC: D06F33/02
Filed: 2001-06-04
Abstract: PROBLEM TO BE SOLVED: To reduce mechanical force applied to wash in a washing process. SOLUTION: Detergent is dissolved with a small quantity of city water to generate high-concentration detergent liquid having detergent concentration of 200-fold to 300-fold. While the high-concentration detergent liquid is diluted to the detergent concentration of 5 to 30-fold, it percolates into the wet wash and sinks therein so that chemical washing force is applied to dirt adhering to the wash to heighten the washing efficiency. After that, in the case of supplying the quantity of water required for washing and washing the wash, mechanical force applied to the wash is reduced to lessen damage and entanglement of the wash.
